Full visual redesign: new BelliedMonkey mascot (icon + floating button), warm terracotta & sage palette across every surface. Translation default color moves from green to sage - a one-shot migration updates old defaults only; any color you chose yourself is never touched. No functional or permission changes.

整套视觉改版：大肚猴新吉祥物（图标 + 悬浮按钮），全部界面换上暖陶土与鼠尾草配色。译文默认色由绿改为鼠尾草——一次性迁移只更新旧默认值，你自己选过的颜色绝不改动。功能与权限零变化。

1.4.1 —— 质量跟进 / Quality follow-up

• 修复：扩展弹窗右侧出现大片空白（Chromium）
• 修复：句子解析对思考型模型返回空结果——预算加大，失败会写明原因与对策
• 新增：解析引擎可独立于翻译引擎配置（默认跟随）
• 全产品交互加固：网络/存储操作进行中按钮明确禁用，杜绝重复触发与重复扣费
• 学习语言选中态改为实心高亮

• Fixed: blank area on the right of the popup (Chromium)
• Fixed: sentence notes returning empty with thinking/reasoner models — bigger budget, named failures
• New: notes engine configurable independently of the translation engine (follows it by default)
• Interaction hardening: controls disable while network/storage work is in flight
• Learning-language selection shows as a solid highlight
